Summing sigma by expanding
WebGiven y= f a;3a;ag, show the left and right sides are equal by expanding the summation notation and simplifying it. Assume that ais an unknown constant. Question 4. X y2 i 11a= 11a(a 1) 1.5 Summation with R Summation: sum(x) Where x is a vector. R Command CAUTION: sum(x^2) = P x2 i where sum(x)^2 = (P x i) 2 Example 2 (Summation in R). Given … WebEinstein introduced a convention whereby if a particular suffix (e.g., i) appears twice in a single term of an expression then it is implicitly summed. For example, in traditional notation x.y = x 1y 1+x 2y 2+x 3y 3= X3 i=1 x iy i; using summation convention we simply write x.y = x iy i. All we are doing is not bothering to write down the P !
